<h1>Simple Testing Example</h1>

<div class="exampleIntro">
	<p>This example shows basic usage of the YUI Test framework for testing browser-based JavaScript code. 
  Two different <a href="/yui/yuitest/#testcase"><code>TestCase</code></a> objects are created and added to a
  <a href="/yui/yuitest/#testsuite"><code>TestSuite</code></a> object. The <a href="/yui/yuitest/#testrunner"><code>TestRunner</code></a>
  is then used to run the tests once the page has loaded.</p>
